I just tried it.  No go.

When I go to the device menu, after alsa it lists:

	PulseAudio (Null Output)

methinks there may be a clue there.

Interestingly, I get:

28 bike:/dev/snd | ds
total 0
drw-rw-rw- 2 root root       60 2009-07-02 11:58 by-path/
crw-rw-rw- 1 root audio 116,  0 2009-07-02 11:58 controlC0
crw-rw-rw- 1 root audio 116, 24 2009-07-02 11:58 pcmC0D0c
crw-rw-rw- 1 root audio 116, 16 2009-07-02 11:58 pcmC0D0p
crw-rw-rw- 1 root audio 116, 17 2009-07-02 11:58 pcmC0D1p
crw-rw-rw- 1 root audio 116, 33 2009-07-02 11:58 timer

So I don't think it's permissions either.  With regard to the mention
of ACLs, getfacl shows:

# file: controlC0
# owner: root
# group: audio
user::rw-
group::rw-
other::rw-

So no ACLs at all.

The only other clue I can find is a lot of these:

Jul  1 19:01:39 bike rtkit-daemon[2554]: Failed to make ourselves SCHED_RR: Invalid argument

Thanks,
